Description

TECHNICAL FIELD [0001] The present invention relates to a coloring composition, a colored cured film, a color filter, a manufacturing method thereof, and a solid-state image pickup device,

The present invention relates to a coloring composition, a colored cured film, a color filter, a production method thereof, and a solid-state imaging device containing a resin having a dye structure suitable for the production of a color filter usable for a solid-state image sensor and a liquid crystal display element.

As a method of producing a color filter that can be used for a liquid crystal display device or a solid-state image pickup device, there is a pigment dispersion method. As the pigment dispersion method, a coloring and radiation-sensitive composition in which pigments are dispersed in various photosensitive compositions is used. There is a method of manufacturing a color filter by using the above method. Specifically, a colored and radiation sensitive composition is coated on a substrate using a spin coater, a roll coater, and the like, followed by drying to form a coated film, and the colored film is obtained by pattern exposure and development of the coated film. The color filter is manufactured by repeating this operation for the desired number of colors.

Since the above-mentioned method uses pigments, it is stable against light and heat, and patterning is carried out by using a photolithography method. Therefore, positional accuracy is sufficiently secured and it has been widely used as a preferable method for manufacturing a color filter for color display and the like.

On the other hand, in color filters for solid-state image pickup devices such as CCDs, more and more finer characteristics are required. With respect to high definition, the pattern size tends to be miniaturized, but it is considered difficult to further improve the resolution by making the size of the pattern finer in the conventionally widely used pigment dispersion method. One of the reasons is that coarse particles in which pigment particles can aggregate in a fine pattern cause color irregularities to occur. Therefore, the conventional pigment dispersion method used up to now in the present situation is not necessarily suitable for applications requiring a fine pattern such as a solid-state image pickup element.

Conventionally, a color filter has been produced using a pigment as a coloring agent, but it has been studied to use a dye instead of a pigment. In the case of using a dye, the following points are particularly problematic. (1) Dyes generally have poor light resistance and heat resistance as compared with pigments. Particularly, there is a problem that optical characteristics are changed due to a high-temperature process when forming a film of indium tin oxide (ITO) which is frequently used as an electrode of a liquid crystal display or the like.

(2) Since dye tends to inhibit radical polymerization reaction, there is a problem in designing a coloring and radiation-sensitive composition in a system using radical polymerization as a curing means.

(3) Dyes usually have low solubility in either an aqueous alkali solution or an organic solvent (hereinafter simply referred to as a solvent), and it is difficult to obtain a coloring and radiation-sensitive composition having a desired spectrum.

(4) It is difficult to control the solubility (developability) of the exposed portion and the unexposed portion due to frequent interaction of the dye with other components in the coloring and radiation-sensitive composition.

(5) When the molar absorptivity (ε) of the dye is low, a large amount of dye should be added. Therefore, other components such as a polymerizable compound (monomer), a binder and a photopolymerization initiator should be relatively reduced in the coloring and radiation-sensitive composition, and the curability of the composition, heat resistance after curing, developability and the like are reduced.

Due to these problems, it has been difficult to form a colored pattern having a dye, which has a fine and thin film structure for a high-definition color filter and has excellent fastness. Further, in the case of a color filter for a solid-state imaging device, it is required to form a colored layer with a thickness of 1 탆 or less. Therefore, it is necessary to add a large amount of dye to the coloring and radiation-sensitive composition in order to obtain the desired absorption, which causes the above-mentioned problems to occur.

In addition, in the case of performing heat treatment after film formation in a coloring and radiation-sensitive composition containing a dye, there is mentioned a migration phenomenon which easily occurs between coloring patterns of adjacent hues or between laminated and overlapped layers. In addition to the dye migration, the pattern tends to peel off in the low light exposure region due to the decrease in sensitivity and the amount of the photosensitive component that contributes to the photolithography property relatively decreases, so that the desired shape or color density can not be obtained due to heat sagging or elution at the time of development There are other problems as well.

As a method for solving such a problem, a method of solving these problems by making a dye into a resin having a dye structure by polymerization has been disclosed (for example, JP2007-139906A, JP2007-138051A, JP3736221B and JP2011-95732A).

However, when a resin having a dye structure is used as a component containing a coloring and radiation-sensitive composition, the present inventors have found that the following problems arise. In other words, when 10% or more of the resin has a low molecular weight component (particularly, a component having a molecular weight of 2000 or less) relative to the peak area of the total molecular weight distribution of the resin, the molecular weight of the low molecular weight component The mobility is large, and it can be clearly seen as a cause of the color loss of the coloring pattern and a deterioration of the heat resistance. Further, since the hydrophobicity of the low molecular weight component tends to increase, a problem as a cause of the residue at the time of development after the pattern exposure can be clarified.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and is intended to achieve the following objects.

That is, a first object of the present invention is to provide a coloring composition capable of suppressing color loss of a formed coloring pattern to form a colored pattern having excellent developability and heat resistance. A second object of the present invention is to provide a colored cured film capable of suppressing color loss of a formed color pattern to form a colored pattern having excellent developability and heat resistance, a color filter having the colored pattern, .

Coloring composition

The coloring composition of the present invention comprises a resin (A) having a dye structure and has a molecular weight of not more than 2000 with respect to the peak area of the total molecular weight distribution of the resin (A) measured by gel permeation chromatography (GPC) The peak area of the component is less than 10%.

The coloring composition of the present invention in which the peak area of a component having a molecular weight of 2000 or less with respect to the peak area of the total molecular weight distribution of the resin (A) measured by GPC of the resin (A) is less than 10% And a coloring pattern having excellent developability and heat resistance can be formed. The reason is not clear, but is estimated as follows. When a color filter is produced, a component having a low molecular weight of 2000 or less in a resin having a dye structure has a large molecular mobility, so that the solvent contained in the adjacent coloring layer and the component tends to elute in the developer in patterning. Therefore, when the low molecular weight component of the resin is present in an amount of 10% or more with respect to the peak area of the total molecular weight distribution, it can be clearly seen as a cause of the color loss of the color pattern. As described above, since the molecular mobility of the low-molecular-weight component is high, a nucleophilic reaction can be caused in a resin molecule having a different dye structure when heating such as prebaking is performed. Therefore, when the low molecular weight component of the resin is present in an amount of 10% or more with respect to the peak area of the total molecular weight distribution, deterioration of the heat resistance of the colored pattern can be clearly observed.

In the resin having a dye structure, the component having a low molecular weight of 2000 or less tends to increase in hydrophobicity. When the amount of the component is 10% or more of the peak area of the total molecular weight distribution of the resin, It is possible to clearly identify the cause of the residue when developing after exposure.

On the contrary, the present invention provides a resin composition which has a peak area of a component having a molecular weight of 2000 or less with respect to the peak area of the total molecular weight distribution of the resin (A) measured by GPC with respect to the resin (A) It is presumed that a coloring pattern having excellent developability and heat resistance can be formed.

The coloring composition of the present invention is preferably a coloring and radiation-sensitive composition having radiation-sensitive properties.

The coloring composition of the present invention preferably further contains a pigment (B) and more preferably contains not only (A) and (B) but also a polymerizable compound (C) and a photopolymerization initiator (D) ) To (D) as well as (E) an alkali-soluble resin, and may contain other components such as a crosslinking agent, if necessary.

Each of the components contained in the coloring composition of the present invention will be described in detail below.

[A resin (A) having a dye structure in which the peak area of a molecular weight component having a weight average molecular weight of 2000 or less measured by gel permeation chromatography (GPC) is less than 10% with respect to a peak area of the total molecular weight distribution of the resin (hereinafter, Simply referred to as "resin (A) having a dye structure" or "resin (A)

In the present invention, the measurement of the weight average molecular weight using GPC can be performed under the conditions described below, and can be set to a conversion value based on polystyrene.

Column: TSKgel Multipore HXL-M (7.8 mm ID x 300 mm L) x 3 (manufactured by TOSOH Corporation)

Eluent: tetrahydrofuran

Flow rate: Sample pump: 1.0 mL / min, Reference pump: 0.3 mL / min

Temperature: Inlet oven: 40 캜, Column oven: 40 캜, RI detector: 40 캜

Measurement sample injection amount: 5 mg of the sample is diluted with 5 mL of tetrahydrofuran, filtered through a 0.5 μm PTTE (polytetrafluoroethylene) membrane filter, and then 100 μL is injected.

The weight average molecular weight of the resin (A) having a dye structure is preferably 4000 to 15000, more preferably 5000 to 10000. When the weight-average molecular weight is very small, the coloring of the formed coloring pattern is a cause of loss of color and deteriorates developability and heat resistance. In addition, if the weight average molecular weight is very large, deterioration of color unevenness increases.

In the present specification, a value measured in terms of polystyrene using the GPC method is used as the weight average molecular weight and the number average molecular weight.

In the present invention, the reprecipitation operation may be performed once, but it is preferable that the reprecipitation operation is repeated a plurality of times. Specifically, it is preferable to repeat the operation of contacting the resin with a poorly soluble or insoluble solvent after the resin is once precipitated and separated, and then the resin is dissolved again in a solvent. In other words, after completion of the polymerization reaction, the resin is contacted with a poorly soluble or insoluble solvent, and then the resin is precipitated (step a), the resin is separated from the solution (step b) (Step c). Thereafter, a solvent in which the resin is poorly soluble or insoluble is added to the resin solution A in a volume of less than 10 times (preferably not more than 5 times) the volume of the resin solution A (Step d) and separating the precipitated resin (step e) by repeating the reprecipitation operation a plurality of times.

As the reprecipitating solvent, a mixed solvent of the refractory agent and a solvent which is soluble or readily soluble in the resin having the dye structure (two-component agent) may be used. Methanol, tetrahydrofuran, N-methylpyrrolidone, 1-methoxy-2-propanol, ethanol and the like can be exemplified as the above-mentioned two kinds of agents, and acetonitrile, methanol, N-methylpyrrolidone, 1- Methoxy-2-propanol or ethanol is preferred, and acetonitrile, methanol, N-methylpyrrolidone or 1-methoxy-2-propanol are more preferred.

Ltd.), and a structure in which these (meth) acryloyl groups are linked through ethylene glycol or propylene glycol moieties. These oligomer types can be used. Hereinafter, preferable forms of the polymerizable compound are shown.

The polymerizable compound may have an acidic group such as a carboxyl group, a sulfonate group or a phosphate group as a polyfunctional monomer. If the ethylenic compound has an unreacted carboxyl group as in the case of the above mixture, it can be used as it is.

However, when the exposure apparatus is damaged by halogen, it is necessary to suppress the addition amount of the polymerization initiator to a low level. In order to form a fine pattern such as a device, it is most preferable to use an oxime compound as the photopolymerization initiator (D).
